The complete diff and merge solution which offers both directory and file comparison, six different diff algorithms and multiple levels of comparison.
In large teams composed either of developers or technical writers, the use of a shared repository for the source or document files is a must. Often many authors are changing the same file at the same time.
Finding what has been modified in your files and folders can be hard. If your data is changing, you can benefit from accurate identification and processing of changes in your files and folders with oXygen XML Diff 's features for comparing files and comparing directories.
These are powerful and easy-to-use tools that will do the job fast and thoroughly. With the possibilities of differencing and merging, it is easy to manage multiple changes.
The comparison of a pair of files is done by opening them in two editors arranged in a side by side layout. You can edit both the source and the target file. The differences are refreshed when you save the modified documents. The comparison and merging can be performed also on files inside ZIP-based archives.
The differences are presented in a graphical format, the scrolling of the two documents is synchronized so the matches are kept close one another. Guiding areas are painted between the two files to allow to easily locate visually the corresponding differences. An overview ruler helps tracking the changes.
The diff solution includes two XML diff algorithms (XML Accurate - tuned for precise compare and XML Fast - tuned for speed at the expense of some accuracy), one Syntax Aware algorithm that gives very good results on all file types known by oXygen XML Diff and three algorithms that rely on the file structure: line based, word based and character based. Any algorithm can be used to perform differences on request, but oXygen XML Diff offers also an automatic selection, selecting the most appropriate one based on the files' content and size.
The XML diff algorithms are designed to help with the necessities that come with XML document comparison. This means that you can specify if namespaces, prefixes, namespace declarations, processing instructions, comments, CDATA, DOCTYPE, the order of attributes or even text elements should be ignored or not.
All the diff operations do not block the user interface, they present progress information and allow the user to cancel them at any time.
The multiple levels diff support allows you to go into a found difference and see further what is actually modified there. The second level diff has the full merging support that is found also in the first level diff.
When there are modifications between the source and the target file you can see them in detail, at word level, by clicking the "Show modification details at word level" button from the Compare menu.
You can also see modifications in even deeper detail, at character level, by clicking the "Show modification details at char level" button from the Compare menu.
Both the compare directory and compare file tools are available as separate applications and also integrated in oXygen's Tools menu.
The diff and merge tool is included in the standalone distribution of oXygen XML Editor.
The directory comparison result is presented using a tree view. The directories that contain different files are expanded automatically, so you can focus directly on the differences. You can merge the directories' content using the copy actions or you can examine the content of the different files. The comparison and merging is also performed inside ZIP-based archives (ZIP, JAR, ODF, OOXML).
When performing a diff between directories/archives the files can be compared by several methods:
The file and folder exclude filters help to easily specify the set of files that will be used during the comparison operation. You can choose to see the differences only from the XML files or XSL files, for instance. By default, the comparison is made on all file types.
If a file or a folder exists only on one side of the compared directories, the name of the file or folder will be colored blue and marked with an "X". If a file exists in both directories but the content is different, the name of the file will be colored red and marked with a "not-equal" sign.
By double-click on a line containing image files a Compare Images dialog will be displayed. The dialog presents the images in the left and right part scaled to fit the view's available area. You can use the contextual menu actions to scale the images at its original size or scale it down to fit in the view's available area. This is mostly useful for visual comparison.
The supported image types are: GIF, JPG / JPEG, PNG, BMP.
